Virgin Trains workers could go on strike in the row over new uniforms that are said to be too ‘skimpy’.

Staff members are set to be balloted over industrial action after the RMT union received complaints from female workers that the outfits were too revealing and ill-fitting.

The union also claimed staff had been told that if they did not like the blouses, they would get £20 to buy a bra.

Last week the transport union TSSA expressed similar concerns about the uniforms.

RMT general secretary Bob Crow said: ‘RMT members are disgusted that in the same week that (Virgin boss) Sir Richard Branson dressed up in a specially-made women’s airline outfit as a publicity stunt, his own staff are being told to wear uniforms that are degrading, undignified and ill-fitting.

‘RMT members deserve to be treated with dignity and respect in the workplace and it is clear the proposed uniform is completely unacceptable.

‘Talks (with management) are continuing but we make it clear that we are quite prepared to ballot all our members for industrial action to ensure they do not have to wear this totally unsuitable uniform.’

A Virgin Trains spokesman insisted the reaction to the new uniforms had been ‘positive’.

‘However, at this stage it is still very much a trial and one that was always intended to generate feedback,’ he added.

‘We are aware of the concerns expressed and are working closely with our staff to resolve them.’
